File system

We recommend you use the static class VirtualFileSystem to access files across platforms. It offers all basic operations such as reading, writing, copying, checking existence and deleting files.

Note

The path separator is / (Unix/Linux convention).

Code example

// Open a file through VirtualFileSystem
var gamesave1 = VirtualFileSystem.OpenStream("/roaming/gamesave001.dat", VirtualFileMode.Open, VirtualFileAccess.Read);

// Alternatively, directly access the same file through its file system provider (mount point)
var gamesave2 = VirtualFileSystem.ApplicationRoaming.OpenStream("gamesave001.dat", VirtualFileMode.Open, VirtualFileAccess.Read);
